Answer:

-22=22

Step-by-step explanation:

3,5-5,7=

-22/22

The equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.

To find the equation of the line passing through the midpoint R and the points P and Q, we first need to find the coordinates of the midpoint R. The midpoint coordinates can be found by taking the average of the x-coordinates and the average of the y-coordinates of P and Q.

The x-coordinate of the midpoint R is (3 + (-5)) / 2 = -1/2.

The y-coordinate of the midpoint R is (5 + 7) / 2 = 6.

So, the coordinates of the midpoint R are (-1/2, 6).

Next, we can use the two-point form of the equation of a line, which states that the equation of the line passing through points (x₁, y₁) and (x₂, y₂) is given by:

(y - y₁) = (y₂ - y₁) / (x₂ - x₁) \(\times\) (x - x₁)

Substituting the coordinates of R (-1/2, 6) and P (3, 5) into the equation, we have:

(y - 6) = (7 - 5) / (-5 - 3) \(\times\)(x - (-1/2))

Simplifying the equation:

(y - 6) = (2 / -8) \(\times\)(x + 1/2)

(y - 6) = -1/4 \(\times\)(x + 1/2)

4(y - 6) = -x - 1/2

Therefore, the equation of the line passing through R and PQ is 4(y - 6) = -x - 1/2.

Answer:

\(dy \ = \ 0.1\)

Step-by-step explanation:

Considering the Leibniz notation to represent the derivative of \(y\) with respect to \(x\), suppose \(y \ = \ f\left(x\right)\) is a differentiable function, let \(dx\) be the independent variable such that it can be designated with any nonzero real number, and define the dependent variable \(dy\) as

                                                  \(dy \ = \ f'\left(x\right) \ dx\),

where \(dy\) is the function of both \(x\) and \(dx\). Hence, the terms \(dy\) and \(dx\) are known as differentials

Dividing both sides of the equation by \(dy\), yield the familiar expression

                                                         \(\displaystyle\frac{dy}{dx} \ = \ f'\left(x\right)\).

Given that \(f\left(x\right) \ = \ x\) and \(dx \ = \ 64.1 \ - \ 64 \ = \ 0.1\), hence

                                                 \(f'\left(x\right) \ = \ 1\).

Subsequently,

                                               \(dy \ = \ f'\left(64\right) \ \times \ 0.1 \\ \\ dy \ = \ 1 \ \times \ 0.1 \\ \\ dy \ = \ 0.1\).

Answer:

C(M) = 0.65*M + 22.55

Step-by-step explanation:

We know that the cost to rent and drive for M miles is given by:

S(M) = 0.40*M + 17.75

And the insurance, also a function of M, is given by:

I(M) = 0.25*M + 4.80

We want to find the equation of the total cost for a rental that includes insurance.

This would be just the sum of the two above functions:

C(M) = S(M) + I(M)

C(M) = (0.40*M + 17.75) + (0.25*M + 4.80)

Now we just need to simplify this:

Taking M as a common factor, we get:

C(M) = (0.40 + 0.25)*M + 17.75 + 4.80

C(M) = 0.65*M + 22.55

Then the total cost equation, as a function of M, is given by:

C(M) = 0.65*M + 22.55

  V = (3.14)(5 cm)²(8 cm) = 628 cm³

Answer:

First choice: (2, 5) (3, 5).
Third choice: (7, -4) (-4, 7) (4, 7)

Fifth choice: (6, 8) (-2, 8) (100, 8), (0.7, 8)

Step-by-step explanation:

If  a(b) is to be a function it must satisfy the vertical line test

What Is Vertical Line Test?

In a vertical line test, you draw a vertical line parallel to the y-axis that cuts the graph. If there is only one point  where it cuts the line, then the equation and the graph represent a function

Putting it in other words, there can be only one y-value for a specific x-value. If a single x-value generates more than one y-value it is not function

As an example look at the attached image (this is from the site CueMath)

The graph on the left is y = x² and you can see that any vertical line cuts the graph at only one point. So y = x² is a function

The graph on the right is x = y² and a vertical line drawn will cut the graph at two points so x=y² or equivalently y² = x is not a function

With this knowledge, let's examine each of the 5 choices given

First option: (2, 5) (3, 5).
This can represent a function since for x = 2 there is only one y value and for x = 3 there is only one y value and that is 5. Do not be confused that the y-values are the same for two different x values.

This could represent a horizontal line on the graph

Second option: (5, 2), (5, 3)
This cannot be a function because for the same x value of 5 we get two different y values, 2 and 3

Third option: (7, -4) (-4, 7) (4, 7)
This can represent a function since for any value of x there is a unique value for y. Again it does not matter that -4 and 4 are two different x values which yield the same y value for the reasons specified under option 1

Fourth option: (7, -4) (-4, 7), (-4, -7)
Cannot be a function for reasons stated under option 2. x value of -4 results in two different values for y

Fifth option: (6, 8) (-2, 8) (100, 8), (0.7, 8)
Can represent a function for reasons stated under option 1

The probability that Jessica picks a yellow pencil is 80%.

What exactly is probability?

Probability is a measure of an event's possibility or chance of occurring. It is stated as a number ranging from 0 to 1, or as a percentage ranging from 0% to 100%, where 0 indicates an impossible occurrence and 1 (or 100%) represents a certain event.

Now,

The probability of picking a yellow pencil =  the number of yellow pencils / total number of pencils:

Probability of picking a yellow pencil = Number of yellow pencils / Total number of pencils

In this case, there are 8 yellow pencils out of a total of 10 pencils:

Probability of picking a yellow pencil = 8 / 10

Simplifying the fraction by dividing both the numerator and denominator by 2, we get:

Probability of picking a yellow pencil = 4 / 5

Probability of picking a yellow pencil = 4 / 5 x 100%

Probability of picking a yellow pencil = 80%

Therefore, the probability that Jessica picks a yellow pencil is 80%.

Answer:

Possible solution 1: -4.5 and -8

Solution 2: 4 and 9.

Step-by-step explanation:

Let the two numbers be a and b.

One of them (let it be b) is 1 more than twice the other one. In other words,

b= 1+ 2a.

Their product is 36. Or:

a(b) = 36.

Substitute b:

a(1+2a) = 36

2a^2 + a = 36

2a^2 + a - 36 = 0

This is now a quadratic. We can factor to solve it. Find two numbers that equals 2(-36)=-72 and add to 1. We can use 9 and -8. Thus:

2a^2 - 8a + 9a - 36 = 0

2a(a - 4) +9(a-4) = (2a+9)(a-4) = 0

So, a = -9/2 = -4.5 or a = 4.

Thus, b can equal 1 + 2(-4.5) = -8 or 1 + 2(4) = 9

The number of sodas sold at the baseball game was 119, while the number of hot dogs sold was 72.

Let's assume the number of sodas sold as 'x' and the number of hot dogs sold as 'y'.

According to the problem, the total number of sodas and hot dogs sold is 191, so we can write the equation:

x + y = 191   ...(1)

The problem also states that the number of hot dogs sold was 47 less than the number of sodas sold. Mathematically, we can express this as:

y = x - 47   ...(2)

To find the values of x and y, we can solve the system of equations (1) and (2). Substituting equation (2) into equation (1), we have:

x + (x - 47) = 191

Simplifying the equation:

2x - 47 = 191

2x = 191 + 47

2x = 238

Dividing both sides by 2:

x = 238/2

x = 119

Substituting the value of x back into equation (2):

y = 119 - 47

y = 72

As a result, the total amount of sodas sold is 119, and the total amount of hot dogs sold is 72.

The number of degrees below zero is given by A = 56° F

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the initial temperature be represented as T

Let the number of degrees below zero be A

Now , the value of T is

Answer:

is this actually a question?

Step-by-step explanation:

Answer: The two numbers that multiply to -65 and add to -8 are -13 and 5.

Steps: Here are the steps to find two numbers that multiply to -65 and add to -8:

Write down the equation x * y = -65 where x and y are the two numbers you’re looking for.

Write down the equation x + y = -8.

Solve for one of the variables in one of the equations. For example, solving for x in the second equation gives us x = -8 - y.

Substitute this expression for x into the first equation: (-8 - y) * y = -65.

Solve this quadratic equation for y: -y^2 - 8y + 65 = 0.

Use the quadratic formula to find the values of y: y = (-(-8) +/- sqrt((-8)^2 - 4 * (-1) * 65)) / (2 * (-1)).

This gives us two possible values for y: -13 and 5.

Substitute these values back into one of the original equations to find the corresponding values of x. For example, when y = -13, we have x = -8 - (-13) = 5. When y = 5, we have x = -8 - 5 = -13.

So, the two numbers that multiply to -65 and add to -8 are -13 and 5.
